Textile oil



Patented Aug.16, 1932 UNITED STATES PATENT OFFICE rmnarcx w. SULLIVAN, .m, or wmrme, minim, nssrcuon 'ro srnmm on. comm, or wmmo, mnmmnn conrom'non or nmrnu TEXTILE 011 I Drawing.-

The present invention relates improve and knitting machines, and for lubrication of the parts of the latter.

In accordance with the present invention I prepare a textile oil by admixing with a suitable textile lubricant oil such as purified m mineral oil of low viscosity, lard oil, purified degras or compounded oils, an emulsifying agent such as an alkali metal soap, a sulfonated fatty oil compound or an alkali metal salt of a preferentially oil soluble sulfonic acid 16 derived from the treatment of a mineral oil with stron or fuming sulfuric acid. To the mixture add 0.1 to 2.0% of a suitable antioxydant, such as beta-naphtho'l, diphenylamine or the like. Thus a suitable composition at prepared in accordance with my invention and particularly! suitable for use on rayon' may contain from 12 to 15% ofa sulfonic acid soap of the character hereinbefore described,

12 to 15% of oleic acid,2% of beta-naphthol $5 and the remainder of mineral oil of the character above described. In use the oil may be diluted with an oil of a lower viscosity until the mixture has a desired viscosity below 7 0 sec. Saybolt (100 F.) (for example, cleaners naphtha). The proportion of diluent required may vary from 5 to but in general, none is required. It is readil apparent that a considerable proportion 0 this diluent evaporates 'from the treated rayon.

The textile fiber is treated with the oil,

suitably in skein form. Thus, the skeins of 1 the fibers may be immersed in a bath of the above oil and subsequently centrifuged to remove excess oil, or the oil may be distributed through the skeins, after being sprinkled thereupon, by capillary action.

It has been found that the softening and lubricating agents ordinarily used on other fabric materials than rayon cannot be used upon the latter material, by reason of an excessive and permanent wea ening of the ragon fiber, discoloration of the fiber, great di culty in subsequent removal in washing, and other ditficulties which apparently arise out of the peculiar character of the rayon fiber.

Application fled December 8, 'sei-lal Io. 158,781.

These diificulties, are to a large part, removed by the use of an oil of the nature described in the co-pendin application of Ansel M. Kinney, Serial 0. 158,834, filed January 1927, upon the composition of which the present invention is an improvement. By the use of the present invention, in connection withsuch oils, the product may be used at any time within a substantial period after manufacture without' causing discoloration or otherpermanent defects in the rayon fiber or the articles woven therefrom. A similar result is secured by' the use of the resent invention in connection with oils suita le for use on other textiles.

I claim:

1.. A lubricatingmcom osition for the treatment of textile fi rs or weaving, knitting and the like comprising an oil, an emulsifying agent and a small proportion of an antioxydant.

2. A lubricating compostion for the treat- -ment of rayon for weaving, knitting and the like comprising analkali metal soap of a sulfonic compound derived from mineral hydrocarbon oils, oleic acid, a mineral oil and a small proportion of an anti-oxydant.

3. A lubricatingcomposition for the treatment of ra on for weaving, knitting and the like comprlsing an alkali metal soap of a sulfonic compound derived from mineral hydrov carbon oils, oleic acid, a mineral oil and betanaphthol.

4. A lubricatin com osition for the treat-.

ment of textile fi rs or weaving, knittin and the like comprising an oil, a sulfonate oil body as an emulsifying agent, and a small proportion of an anti-oxydant.

5. The method of preparing rayon fiber for weaving, knitting and the like which comprises incorporating therein an oil, an emulsifyin agent, oleic acid and a small proportion 0 an anti-oxidant.

6. The method of preparing rayon fiber for weaving, knitting and the like which comprises incorporating therein an oil, an emulsifying agent, oleic acid and 0.1% of beta na htho Y 7 The method of preparin rayon fibre for weaving, knitting and the e, which comprises incorporating an oil therewith, addinfi a preferentially oil-soluble sulfonate deriv from mineral oils as an emulsiizing agent to the oil whereby it may be was ed from the 6 fibre, and employing a small portion of antioxidant for preventmg the deterioration and loss of strength of the oiled rayon fibre. 8. The method of claim 5 wherein the emulsifying agent comprises a sulfonic compound '10 derived from mineral hydrocarbon oils.
